LAND-PACKER.

To all whom it may concern:

Be it known that I, ALBERT E. SMITH, of the town of Yorkton, in theProvince of Saskatchewan, Canada, have invented certain new and usefulImprovements in Land- Packers, of which the following is thespecification.

My invention relates to a land packer and the object of the invention toprovide an attachment which can be applied to the usual form of diskharrov whereby the har rows are converted into land packers therebyavoiding the necessity of having two distinct and costly machines.

A further object is to provide a packer which can be used both as asurface and a subsurface packer and which can be made to fit any form ofdisk harrow that is at present on the market.

The invention consists essentially in a rim formed of two sectionsadapted to be secured together and placed over the disk of a harrow, theparts being arranged and constructed as hereinafter more particularlydescribed.

Figure l is a side elevation of a disk showing my invention applied.Fig. 2 is a front elevation of two disks on the harrow shaft both ofsuch disks being fitted with my rim, one of them being shown in verticalsection. Fig. 3 is a vertical sectional view through a disk on a harrowshaft showing a modified form of the rim employed to avoid interferingwith the usual harrow tilting bar.

In the drawings like characters of reference indicate correspondingparts in each figure.

1 represents the main shaft on which the disks are secured, such shaftbeing of any desired type either round or square.

2 represents the harrow disks which are threaded on the shaft and spacedapart by the sleeves 3, such sleeves being each provided with enlargedends a and 5, the ends 5 being designed to abut the concave faces of thedisks and those 4 the convex faces. In this way each disk is held in adefinite position on the shaft between the adjoining ends 4: and 5 ofeach successive pair of sleeves.

6 represents a cast iron or other such metal- Speeification of LettersPatent.

lic rim which is formed in the present instance from two sections 6 and6 each section having its inner side fashioned at 7 so as to receivesnugly the circumferential edge 8 of the disk, and its outer sidegradually tapering to an edge at 9 which is designed to cut into thesoil. The sections 6 and 6 are provided each with lugs 10 which arecored out centrally so as to admit bolts 11 by which the sections can befastened together securely when spaced around the disks.

12 are wings appearing on the sections, such wings extending outwardlyfrom the faces of the rims and being all concentric to the shaft 1.Their purpose is to partially pack and pulverize the earth with whichthey come into engagement when the rim is rotated.

The lugs 10 are of the same form as the wings so that when two of themare brought together they fulfill the same purpose as a wlng.

In the modified form of rim shown in Fig. 3 it will be seen that thelugs 10 at the left hand side of the post instead of being horizontallydisposed are vertically disposed as at 10 so as to clear the ordinarytilting bar 13 of the usual disk harrow which is fastened to the shaft 1by means of a sleeve 14. The lugs 10 of each section are fastenedtogether by bolts in the same manner as are the lugs 10, the boltspassing through the openings 10 provided.

WVhat I claim as my invention is l. The combination with a disk of asectional rim adapted to be detachably secured to the disk inclosing itscircumferential edge and having extending wings thereon and adapted tocontact with the ground, as and for the purpose specified. V

2. The combination with a disk of a sectional rim adapted to bedetachably secured to the disk inclosing its circumferential edge andhaving laterally extending wings thereon said wings being concentricwith the shaft, as and for the purpose specified.

3. The combination with a disk of a harrow, of an inclosing rim for thedisk comprising tWo or more sections having lugs formed thereon wherebythe sections can be secured together by bolts passing through disk andhaving Wings extending laterally therefrom as and for the purposespecified. 1O Signed at Yorkton, in the Province of Saskatchewan, this4th day of May 1909.

the lugs said sections being provided with 5 laterally extending wings,the Wings and the lugs being similarly constructed on the outer face andlocated an equal distance from the center of the disk, as and for thepurpose specified.

4. In a device of the class described, a rim designed to encircle theedge of a harrow
